The full grown grubs may be anything up to two inches long, according to the species, and are legless, having short strong jaws and small round head.

The Buprestidae, or Jewel Beetles, are well known from their brilliant colouring and are commonly met with during Summer. They may frequently be captured on native shrubs, being attracted thereto by the flowers. In size they range from an eighth of an inch to three inches. The body is elongate in form with short head, large eyes, adbomen covered with long closely-fitting, highly-coloured wing covers.
